| titleOfInvention | A kind of method and device of low-grade coal vanadium extraction pure oxygen roasting |
| abstract | The present invention relates to a kind of method of low-grade coal vanadium extraction pure oxygen roasting, is replaced by two oxygen intakes of roaster furnace bottom and pure oxygen is blown into roaster, the low-grade coal inside roaster burns in the oxygen of Uniform Flow, makes III valency vanadium in low-grade coal fully oxidized；High-temperature flue gas caused by roaster preheats to the pure oxygen before entering roaster, promotes oxidizing fire；Utilize roaster radiation of burner hearth heat production water vapour；The present invention makes the oxygen Uniform Flow inside roaster, and burning is abundant, it is ensured that by III valency vanadium complete oxidation in low-grade coal is acid-soluble V valency vanadium.Radiant heat caused by the roasting of burner hearth internal oxidition is effectively recycled, and reaches energy-saving purpose. |
